Redispersible Polymer Powder (RDP) and HYDROXYPROPYL METHYL CELLULOSE (HPMC) are golden
partners in tile adhesive formulations. Their synergy can create "1+1>2" performance breakthrough.
It forms a high-quality mix of High Performance Tile Adhesive Additives.
This mix solves key problems in ordinary tile adhesives. It helps prevent hollowing, detachment & cracking.
It also meets modern construction needs for high-quality paving materials.
RDP & HPMC Synergy: Functional Core
RDP (Strength & Flexibility):
Forms a tough, flexible polymer film within the cement matrix, creating an interpenetrating
network that boosts bonding, prevents detachment & enhances durability.
HPMC (Workability & Retention):
Manages water by slowing hydration and minimizing loss. This prevents cracking,
improves sag resistance & ensures smoother, more efficient application.
Combined Result:
Together, they deliver superior water resistance, freeze-thaw stability and weather resistance,
meeting the demands of diverse indoor and outdoor tiling projects.
In modern construction, high-performance paving materials are in great demand.
Ordinary cement-based adhesives often fail to meet requirements because of
weak bonding strength and poor durability. This can affect overall construction quality.
The optimal solution is the synergistic use of Redispersible Polymer Powder (RDP) and
HYDROXYPROPYL METHYL CELLULOSE (HPMC).
This combination can comprehensively upgrade the performance of the adhesive,
making it more reliable and durable.

Jinan Jintedifu Chemical Co., Ltd. is a leading maker of Redispersible Polymer Powder (RDP) and
Hydroxypropyl Methyl Cellulose (HPMC). Its annual RDP production capacity is 20,000 MT.
The company offers JINT Series RDP & high-quality HPMC products. These are essential raw materials
for high-performance tile adhesives. They are also key examples of high-performance tile adhesive additives.
The two products are professionally designed for synergy, ensuring perfect compatibility and stable performance.
Together, RDP & HPMC bring four key benefits to the adhesive.
- They provide strong bonding strength for firm adhesion of many tile types.
- They offer superior flexibility to handle temperature changes and building movement.
- They improve workability to boost construction efficiency.
- They add long-term durability to extend the paving project's service life.
Choosing the right Redispersible Polymer Powder (RDP) and Hydroxypropyl Methyl Cellulose (HPMC)
helps improve tile adhesive performance.
For RDP, the focus is on the TG value (glass transition temperature).
This value directly determines its flexibility and ability to adapt to different environments.
For HPMC, the main selection factors are viscosity and substitution degree.
A substitution degree of 2.0 to 2.4 ensures good compatibility with RDP. This helps maximize the synergy effect.
Specifically, RDP with a lower TG value (≤0°C) offers better low-temperature flexibility.
Suitable for cold regions, underfloor heating systems, and similar scenarios.
It works best with high-viscosity HPMC (100,000-200,000 mPas).
This improves water retention and helps prevent cracks.
Cracks can occur in low temperatures or when water dries too fast.
RDP with a higher TG value (≥10℃) is more rigid and wear-resistant.
Suitable for exterior walls and high-traffic commercial areas.
We match it with medium- or low-viscosity HPMC to balance workability and structural strength.

Jinan Jintedifu Chemical Co., Ltd. Provides one-stop solutions for
Redispersible Polymer Powder (RDP) and Hydroxypropyl Methyl Cellulose (HPMC).
It ensures both products are compatible and have stable quality.
You can also customize them to fit each customer's adhesive formulation needs.
